Abstract:
Young adolescents were assessed with regard to cognitive, socio-cultural and behavioral components of eating disturbances. An anonymous questionnaire was administered to 5th-8th grade pupils, 280 girls and 251 boys, to assess eating habits, body image, self-confidence, environmental-cultural influences, risk behaviors and socio-economic state. Girls scored consistently higher on all weight-control behaviors. Discontent with own body, and attitudes and behaviors associated with eating disorders, were reported by under-studied populations such as boys and younger girls. Both frequency and severity of weight-control behaviors were associated with "social age." Highly significant differences between scores of 6th and 7th graders indicate that they may be at a time of increased susceptibility. Measuring the influence of the mass media gave inconsistent results.
